Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an air conditioner suitable for implementation as a so-called window type air conditioner.

[Conventional technology]

As a type of air conditioner, a window-type air conditioner is widely used, which is mounted on a wall window with a part of the housing exposed both indoors and outdoors.

Conventionally, this type of air conditioner was manufactured in U.S. Pat.
It is disclosed as No. 1 and is structured as shown in FIG. To explain this based on the same figure, wall 1
The housing 3 of the air conditioner 2 installed in the air conditioner 2 is formed in the shape of a rectangular box, and approximately half of its total length is exposed to the outside. Inside the room of the housing 3, there is a cooler 4.
and an indoor blower fan 5, and a V-shaped condenser 6 and an outdoor blower fan 8 directly connected to a motor 7 are provided outside the room. A compressor 9 is connected to the cooler 4 and the condenser 6 through piping, and the cooler 4 and the condenser 6 are connected through another piping. 1
0 is a dew pan, 11 is a blowout port, and 12 is a blowout nozzle.

In an air conditioner configured in this way,
When the motors for both fans 5 and 8 and the compressor 9 are started, the refrigerant circulating in the pipes is repeatedly evaporated and condensed by the compressor 9, and the air blower fan 5 inside the room Indoor air sucked in from the side suction port is cooled by the cooler 4 and then sent to the air outlet 11.
It is blown out into the room. In addition, the outdoor air sucked in from the suction port on the side of the housing 3 by the blower fan 8 outside the room is heated by removing heat from the refrigerant gas passing through the condenser 6, and then passed through the blowing nozzle 12 to the outside. It is blown out.

During cooling performed in this manner, the air that is blown up by the blower fan 5 and passes through the cooler 4 is cooled and condensed and collected in the exposure tray 10 to become drain water.
This drain water is then scattered by the blower fan 8 and used for heat radiation from the condenser 6.

[Problem that the invention attempts to solve]

However, in conventional air conditioners, water droplets of drain water blown away by the wind pressure of the blower fan 8 often scatter outside from the lattice part of the blow-off nozzle 12 and wet objects around the outside of the housing room. There was also the inconvenience that drain water was wasted.

The present invention was developed in view of these circumstances, and allows the drain water blown away by the wind pressure of the blower fan to be quickly collected into the housing through the air outlet and reused for heat radiation from the condenser. To provide an air conditioner that can prevent surrounding objects outside a housing room from being wetted by drain water.

[Means for solving problems]

The air conditioner according to the present invention has a large number of ribs arranged concentrically and radially around the center of the air outlet of the blower fan, and a hole for collecting drain water passing through the center. A drain water recovery weir is installed below the hole, and the upper and lower ribs are set so that the radial ribs are higher than the annular ribs, and the left and right ribs are set so that the radial ribs are lower than the annular ribs. It is.

[Effect]

In this invention, water droplets of drain water adhering to the upper concentric ribs are transmitted to the upper radial ribs, flow into the drain water recovery hole, and then pass through the back side of the center part to the lower radial ribs. It was transmitted to
Drain water is collected into the housing from the drain water collection weir. On the other hand, water droplets of drain water adhering to the left and right radial ribs travel along the left and right concentric ribs, flow into the lower radial ribs, and are collected into the housing from the drain water recovery weir.
